Case plans to open his 16th dealership on Sunday, Dec. 1. The Volkswagen store will be in an eight-story building in Davie, Fla. Case, 71, draws buyers by doubling the manufacturer's warranty at each of his stores. And vehicle buyers at six dealerships get discount gasoline and free lifetime car washes. Case also is a stickler for employee training. New salespeople must not have worked at other dealerships, and they spend a month in training before they can sell to customers. Case expects daily training of employees, mostly online but also in classrooms at his stores. Says Case: "Training is the best investment you can make."
